Sister in-law seduction

My in-laws live a few blocks away from me. A summer in Arizona is hellish. At least 3 times a week I go over to my in-laws for a quick dip in the pool after work. My sister in-law fell on hard times with this economy and was forced to move back home with her parents. Trina is a short Mexican girl who looks a little Asian, but is kind of attractive. She has a little extra weight but it is in all the right places, mainly her chest. For a 5'0'' girl with a DD chest, it's hard not to notice.

I usually go to their house straight from work and change into my bathing suit there. Today was no different. I left my work clothes in the bathroom and headed out to the pool. Trina was already in the pool with a big margarita. She was wearing this great looking blue bikini. Her chest looked absolutely amazing. I went out and had some nonchalant conversation with her, the whole time I was trying not to stare at her breasts overflowing in her bikini top.

After about 45 minutes I decided to get out and go home. Trina said she was going to make another margarita and asked if I wanted one. I agreed, and I sat at the kitchen island while she made the drinks. She poured us both big glasses. I took a drink and commented on how she makes good strong margaritas.

"I love tequila, I always make my margaritas strong. I'm feeling pretty good though, this is my third one." Trina said.

I slowly drank mine and sat at the island. Trina remained standing and just leaned forward on the counter. This gave some nice glimpses of her chest. As we got to talking more she commented on how she had just gotten her bikini and spent half a day looking for a bikini she liked.

"I think it looks really good on you" I said.

She smirked a little and said,"I know why you say that."

"Why is that?" I asked.

"The top to this is a size too small and my boobs are struggling to stay covered."

"That's not why I said it but now that you mention it you are kinda revealing a lot of your chest."

She laughed and said,"Well your not complaining are you?"

I stared at her chest and laughed and said,"No!"

She smirked and stayed leaning over the counter.

I finished my drink in a hurry because I could feel myself starting to pitch a tent in my swim trunks. I got up to go to the bathroom to change back into my clothes. I tried my best to cover up the bulge in my trunks. As I stood up I saw her look right at my semi-hard cock. I saw her smile a little as I walked away.

I got to the bathroom and took off my trunks to change. My cock was rock solid from the view I was getting and the fact that Trina seemed to like it that I was checking her out and that it got me aroused. I jumped in the shower for a quick rinse off and was drying myself off when she barged in the bathroom and saw me naked standing there.

"I'm sorry, I didn't think you would be naked. I wanted to see if you wanted another margarita."

She was saying this to me but looking at my cock. With the liquid courage that I had from my first drink, I didn't even try to cover up my once again semi hard cock. She took a step closer to me.

"You are not all that shy are you?" she said.

"Not really, its just a dick. I'm sure you've seen one before." I said.

She took another step towards me and was clearly turned on by what she saw. "It has been awhile since I have though." As she said this, she took another step closer to me and reached out and grabbed my cock. She stood there and sort of admired my cock and she moved it around in her hand and fingers. Her doing this got me fully erect.

She started to slowly stroke my cock. I reached up and started to rub her tits. "This top hurts my tits, take it off of me." she said. I listened to what she said and undid the back of her bikini top.

She let her top fall to the floor revealing her huge tits and very hard, dark nipples. I started pinching her nipples as she backed to the bathroom sink and leaned back on it, sticking her chest out. I went straight to her nipples and started licking, sucking and nibbling them. She started moaning. I paid a few minutes of attention to each nipple until she reached back down to my cock.

Being fully erect she looked up at me, smiled, and kissed me very passionately for a minute. With my cock in her hands she looked me in the eyes and said very seductively,"What do you want me to do with this?

"Put it in your mouth." I said.

"Just what I was thinking." She said.

She dropped to her knees and slowly licked my cock from the base to the tip before wrapping her lips around it. She slowly got my cock wet from her saliva before she sped up the pace of her blowjob. She kept sucking me until I was going to cum. When I told her I was cumming, she deep throated my whole cock and started rubbing my balls. This was the final straw and I came very hard. I shot my whole load down her throat.

I stopped convulsing from my orgasm she sucked the rest of my cum out of me. After a few minutes of her slowly stopping, she stood up, grabbed her bikini top and said, "I don't know what came over me. We can't tell anyone about this." I agreed with her and she left the bathroom.

I finished getting dressed and told her goodbye. She asked when the next time I was going swimming. I told her within the next few days.
